Tips for cosmetic plastic tube
Mechanical properties of cosmetic plastic tube:
Impact resistance, puncture resistance, flexibility, and tensile strength above 10MPa. Chemical stability of cosmetic plastic tubes:
A.Not affected by water at room temperature;
B.Resistant to most dilute acids;
C.-Generally not affected by aldol, ketone and esters;
D. Less affected by halogen at room temperature;
E. At room temperature, it will cause a certain degree of swelling due to the action of aromatic hydrocarbons, aliphatic hydrocarbons, and halogen hydrocarbons;
F. Slightly absorbs oil, mineral oil and essential oil will escape through polyethylene;
G. Stress cracking may occur under the action of stress cracking agent. Common stress cracking agents include detergents, soaps, oils, fats, alkali metal hydroxides and so on.
Weather resistance of cosmetic plastic tube:
Under the action of ultraviolet and high-energy radiation, it will degrade in the air, resulting in discoloration, surface cracking or even embrittlement, loss of strength and loss of use value. Weather-resistant formula should be used, that is, UV absorber, light shielding agent or light quenching Extinguishant, etc.
